Khetha ukuhluza kwe-EMI kwiibhodi zamaleko amaninzi ukunciphisa ukuphazamiseka

Ungayikhetha njani i-electromagnetic radiation kunye ne-EMI yokucoca itekhnoloji efanelekileyo kwiibhodi ezinamaleko amaninzi ukunciphisa ukuphazamiseka kwezinye izixhobo kunye neenkqubo

Intshayelelo:

Njengoko ukuntsonkotha kwezixhobo zombane kuqhubeka ukwanda, imiba ye-electromagnetic interference (EMI) ibaluleke ngakumbi kunangaphambili. I-EMI inokuchaphazela kakubi ukusebenza kweenkqubo ze-elektroniki kwaye ibangele ukungasebenzi okanye ukungaphumeleli. Ukusombulula le ngxaki, imitha ye-electromagnetic radiation kunye netekhnoloji yokucoca i-EMI ibalulekile kwiibhodi zamanqanaba amaninzi. Kule post yebhlog, siza kuxoxa ngendlela yokukhetha itekhnoloji efanelekileyo ukunciphisa ukuphazamiseka kwezinye izixhobo kunye neenkqubo.

1. Qonda iintlobo ezahlukeneyo zokuphazamiseka:

Ngaphambi kokungena kwinkqubo yokhetho, kubalulekile ukuba ube nokuqonda okucacileyo kweentlobo ezahlukeneyo zokuphazamiseka. Iindidi eziqhelekileyo zibandakanya i-EMI eqhutywe, i-radiated EMI, kunye ne-EMI yexesha elifutshane. I-EMI eyenziwayo ibhekisa kwingxolo yombane eyenziwa ngamandla okanye iintambo zomqondiso. I-radiated EMI, kwelinye icala, ngamandla ombane asasazwa kumthombo. I-EMI edlulayo ibandakanya amandla ombane wequbuliso okanye izikhewu zangoku. Ukumisela uhlobo oluthile lokuphazamiseka ojongene nalo kuya kunceda ukunciphisa iteknoloji yokucoca efanelekileyo.

2. Qinisekisa uluhlu lwamaza:

Izixhobo zombane ezahlukeneyo zisebenza ngamaza ahlukeneyo. Ke ngoko, kubalulekile ukumisela uluhlu lwefrikhwensi apho uphazamiseko lwenzeka khona. Olu lwazi luya kunceda ekukhetheni iindlela ezifanelekileyo zokucoca ezihambelana noluhlu lwamaza okuphazamiseka. Ngokomzekelo, ukuba ukuphazamiseka kwenzeka kwiifrikhwensi eziphezulu, i-band-pass filter inokufaneleka, ngelixa ukuphazamiseka kwe-low-frequency interference kungafuna i-low-pass filter.

3. Sebenzisa iteknoloji yokukhusela:

Ukongeza kwitekhnoloji yokucoca, itekhnoloji yokukhusela nayo ibalulekile ekunciphiseni ukuphazamiseka. Ukugquma amacandelo abuthathaka okanye iisekethe ezinezixhobo zokuqhuba kunokunceda ukuvala imitha ye-electromagnetic. Iitoti ezigqunywe nge-conductively okanye ezikhuselwe yintsimbi zihlala zisetyenziselwa le njongo. Xa ukhetha izinto ezifanelekileyo zokukhusela, qwalasela izinto ezifana ne-conductivity, ubukhulu, kunye nokulula kokudibanisa kwiibhodi ezininzi.

4. Funa ubuchule kuyilo lwebhodi ye-multilayer:

Ukuyila iibhodi ze-multilayer ezinciphisa uphazamiseko kufuna ubuchule bokuyila kunye neendlela zokwenza. Ukusebenza kunye nochwephesha ojongene noyilo lwebhodi ye-multi-layer kunokunceda ukuchonga iindawo ezinokubakho zokuphazamiseka kunye nokwandisa ukucwangciswa kokunciphisa imiba enjalo. Ukubekwa kwecandelo ngokufanelekileyo, ukuqwalaselwa kweplanethi ephantsi, kunye nokulawulwa kwe-impedance routing zezinye zezinto eziphambili ezinegalelo kuyilo lwebhodi ye-multilayer.

5. Vavanya kwaye uqinisekise:

Nje ukuba ubuchule bokucoca kunye nobuchule bokuyila buphunyeziwe, kubalulekile ukuvavanya kunye nokuqinisekisa ukusebenza kwesisombululo esikhethiweyo. Uvavanyo lunokwenziwa kusetyenziswa i-EMI receiver kunye ne-spectrum analyzer ukulinganisa isixa sokuphazamiseka okukhoyo. Eli nyathelo liya kunceda ukuchonga naluphi na uphuculo olongezelelweyo olunokufuneka kwaye luqinisekise ukuba iteknoloji ekhethiweyo ngokwenene iyanciphisa ukuphazamiseka kwezinye izixhobo kunye neenkqubo.

Isishwankathelo

Ukukhetha i-electromagnetic radiation echanekileyo kunye neendlela zokucoca ze-EMI kwiibhodi ze-multilayer kubalulekile ekunciphiseni ukuphazamiseka kwezinye izixhobo kunye neenkqubo. Ukuqonda iintlobo zokuphazamiseka, ukumisela i-frequency ranges, ukusebenzisa iindlela zokukhusela, ukufuna ubuchule kwi-design board ye-multilayer, kunye nokuvavanya kunye nokuqinisekisa izisombululo ezikhethiweyo zizo zonke iindlela ezibalulekileyo kule nkqubo. Ngokulandela ezi zikhokelo, unokuqinisekisa ukusebenza kakuhle kunye nokuthembeka kweenkqubo zakho zombane ngelixa unciphisa iziphumo ezibi zokuphazamiseka kwe-EMI.
